That last little bit about thinner and being just as strong being able to slice. Any task requiring slicing in a survival, woodscrafting and the likes situation will not be master chef grade slicing. My thickest of knives can do the thinnest of slicing, you've seen it. I fully convexed my full flat grind falcon and I can lay it on the surface of anything and make extremely thin slices of anything after batoning enough wood to burn several hours. It's extremely easy to maintain in the field too with improvised methods, easier than 1095 and the edge lasts as long. Thinning out a blade too much will have a constant negative, mass. You shed mass you will need to do other tasks. So thin may be as tough in another steel but you just paid Peter by robbing Paul. Only thing I see a tougher steel being better in is a puukko or small blade where mass is not a characteristic needed to do work it's intended to. At that point all you get is more toughness, it still won't do what the lesser steel can't. You might also make a requirement to carry extra tools to maintain it, robbing Peter to a pay Paul this time there will always be a trade off. If I got a large blade 3V chopper baton duty blade I would not get a thinner one, the mass is needed to do that job, a carbon steel blade will last two days doing heavy work so why put a better steel in a large chopping splitting blade? You still need that mass.
I see what your getting at, I just see it different. Put the 3V in a smaller blade and make it tougher for its already designed thickness. I don't see it working the other way around thinning out a large blade needed for brute force.
To some extent I agree with what you're saying. Most of what I said does apply to smaller knives (if we're talking overall thickness). Like you said, thinking out a larger knife would reduce chopping power, etc. And thicker knives to act more like a wedge, this is true. So if that is an important design feature, that might not be a good idea.
The other thing that the fancy steels "should" let you do is run the edge thinner, or support a more acute edge angle while retaining the same edge stability.
Anyway, I was more trying to convey was my preferences on what id like a knife that was designed for general outdoors use to be capable of, than bring up too much about "super" steels, my bad.
Carry on
